posted Dec 26, 2012, 4:13 PM by Luke Hizer   [ updated Feb 28, 2013, 7:15 PM ]
Update: Here are the minutes from the discussion about the West Duwamish project.

Time: 6:03 p.m.
Topic: West Duwamish Trail Status Update
Presenter: Terry Plumb, SDOT Capital Projects & Roadway Structures Division
Purpose: Project update on the development of West Duwamish Trail in South Seattle

Findings / Critical Points:
Project extends existing West Duwamish Trail from W. Marginal Way South/S.
Holden Street to 8th Ave South along S. Portland Street

Meeting Minutes
-Trail will be on the south side of S. Portland Street and will be 10’ paved wide with 5’
landscaped area between travel lane and 5’ buffer between building face.
-The Trail will be lighted with non‐typical 20 foot poles (non‐cobra head) to light path and
-Along the east side of W. Marginal Way S., between S. Holden St. and S. Portland St., the 10’
Trail will be separated from the roadway by jersey barrier on the west and a small shoulder
and fence on the east.
-SPU will also include drainage as part of this project;
-Construction of the Trail is scheduled for August 2013; the roadway adjacent to the Trail will
be repaved in 2014, as part of complete streets

SBAB Comments/Questions:

Q: Concerned about sight distance with the barrier near the intersection of W. Marginal Way
and S. Holden?
A: The barrier should be set back enough and low enough to not block safe sight distance.

Q: How are the cross‐streets with the Trail treated?
A: Road is narrowed to allow better sight distance and to help slow traffic down traffic.

Q: Can signals be installed at specific locations?
A: Terry couldn’t answer but suggested that this can be part of the BMP Update.

Q: Can trail width be more than 10’?
A: Site conditions suggest a 5’ minimum space between Trail and building face and the
landscaped areas need 5’ for planning. Therefore, not much too give.

Q: What happens at the end of the project? What kind of treatment is proposed?
A: The end treatments will be developed with special attention to safety.

Q: Has consideration been made to connect to the new South Park Bridge, Green River Trail?
A: Not at this time but ultimately King County may/will look to connect.

SBAB recommendations:
SBAB recommends that the width of the trail be widened to 12’ wherever possible, either by
narrowing the automobile travel lane widths or by reducing the buffer between the building
face and the trail from 5’ to 3’.
